### Making Up the Rules: Three Postulates of Quantum Mechanics

If Hψ=eψ, why can't you just cancel the ψs? Operators, rules that change one function into another, play a key role in quantum chemistry. Each measurable quantity has a corresponding operator, and the operator, used in tandem with the wavefunction, can be used to calculate expected values of these quantities. We introduced the notion of the wavefunction as a vector in a function space and used Dirac's bra and ket notation to express the wavefunction and the expectation value.

Michelle,

I just finished reading the book Teleportation by David Darling. Your students might be interested in reading about the most recent applications of quantum mechanics for quantum computation, quantum cryptography and teleportation.
